Had perianal abscess surgery two holes now by my anus said i need sitz bath then to repack wound. i have well water worried n. fowleri infection wound?

Here are some...: The surface of an open wound always harbors some environmental bacteria or yeasts, but which would not make us sick since it is open to air with no way to get into the body but out of body through sitz bath with/without whirlpool to cleanse the wound with some debridement effect to facilitate wound healing. So, it is okay. More? Ask your surgeon.
